Cleaning and lubricating shrink disks

Soiled shrink disks must be cleaned and regreased prior to fitting.
Shrink disks that have been released need not be disassembled and regreased before being
retensioned.
Procedure
1. Only grease the inner friction surfaces of the shrink disks. To do this, use a solid lubricant
with a friction coefficient of μ = 0.04.
2. Use a paste containing MoS
underneath the head.
Clean the shrink disk.
